Method Details

transformScale

public static PixelTransformAffine_F32 transformScale(ImageBase from,
 ImageBase to,
 @Nullable
 @Nullable PixelTransformAffine_F32 distort)

Computes a transform which is used to rescale an image. The scale is computed directly from the size of the two input images and independently scales the x and y axises.

transformRotate

public static PixelTransformAffine_F32 transformRotate(float x0,
 float y0,
 float x1,
 float y1,
 float angle)

Creates a PixelTransformAffine_F32 from the dst image into the src image.

Parameters:

x0 - Center of rotation in input image coordinates.

y0 - Center of rotation in input image coordinates.

x1 - Center of rotation in output image coordinates.

y1 - Center of rotation in output image coordinates.

angle - Angle of rotation in radians.

rotateCenterAffine

public static Affine2D_F32 rotateCenterAffine(float x0,
 float y0,
 float x1,
 float y1,
 float angle)

Creates a PixelTransformAffine_F32 from the dst image into the src image.

Parameters:

x0 - Center of rotation in input image coordinates.

y0 - Center of rotation in input image coordinates.

x1 - Center of rotation in output image coordinates.

y1 - Center of rotation in output image coordinates.

angle - Angle of rotation in radians.

createDistortPL

public static <Input extends ImageGray<Input>,
Output extends ImageGray<Output>>
ImageDistort<Planar<Input>,Planar<Output>> createDistortPL(Class<Output> outputType,
 PixelTransform<Point2D_F32> dstToSrc,
 InterpolatePixelS<Input> interp,
 boolean cached)

Creates a ImageDistort for the planar images of the specified image type, transformation and interpolation instance.

Parameters:

dstToSrc - Transform from dst to src image.

interp - Which interpolation algorithm should be used.
